.To all whom 'it may concern: n

Be 1t known that I, CHARLES COLE, a citij zen of Canada, residing at Chicago, in the scriptio'n, that Willena'ble others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to an improved hydrocarbon-burner5 and it consists of a peculiar device for burning petroleum and other oils in the generation of steam, and for the various purposes in which an invention of -this character could be used.

the former has passed through the burner,

the steam being conducted to the mouth of the burner through a separate passage, and so arranged that no matter how small the n blaze may be it cannot be extinguished by the action of the steam.

Figure 1 is a side elevation and longitudinal section of a device embodying my improved features; Fig. 2, a horizontal section in plane 2, Fig. l; Fig. 3, a vertical transverse section in plane 3, Fig. l; and Fig. 4, a detached detail. Fig. 5 is a longitudinal section and part elevation of a furnace and steam-boiler, showing the relative position of my improved device.

FSO

Referring to the drawings, A represents the oil-supply pipe, A the feed-pipe through which oil is conducted io the burner, and A2 the steam-supply pipe.

The burner proper consists of the outside steam-nozzle B, the oil-nozzle C, inclosed by the steam-nozzle, and Vthe valve D, located inside of the oil-nozzle. The steam-nozzle is of a flattened rectangular shape, the top and bottom of the front or outer end being contracted to a Wedge shape, as shown at a a, Fig. l, thereby providing a steam-discharge opening of a rectangular form. The oil-nozzle C is of a form corresponding to and is lo-. cated inside of the steammozzle, leaving the 4.space a between the two nozzles-that is,

`above and below the .oil-nozzle-and thus providing the steam-exit passage. The steam? 1 passes out onlyabove and below and not at: the sides, as illustrated in Fig. 3. rllhe contracted or flattened discharge end a2 a2 of the oil-nozzle projects or extends beyond lthe corresponding companion end 'of the steam-nozzle, as shown in Fig. l. By this ar-V rangement the steam-jet strikes the exterior projecting surface and the top and under side of the oilnozzle at a point bach ofthe oil-exit opening, the'force ofthe steam being checked and at the same time spread into a thin sheet and expanded to more thoroughly unite With the oil-vapors, and results in a more thorough combustion. Another object' of this feature-that of the steam being dis- 1 charged into the furnace j ust back of the oilis to prevent the same from interfering` with fthe uniform operation of the oil-supply, and

also to prevent the steam from extinguish'- ing the blaze, especially when the flame is reduced to a minimum.' The sides of the oil-nozzle bear closely against and have a rabbeted engagement with the inner adjacent sides of the steam-nozzle, as shown in Fig. 3, which feature provides for the adjustment of the oil-nozzle With reference to the steamnozzle and retains the same in proper relative position thereto.

The flat rectangular regulating-valve D is mounted on the inner end of the valve-spindle D', and is located in the oil-chamber a3, inside of the oil-nozzle. The ends of this valve are rabbeted into the sides of said nozj zie, With the front edge seating in the con tracted oil-outlet, as shown in Fig. 1, the oil passing out above and below the valve, in a like manner with the steam-supply arrangeinent.

The valve spindle D passes centrally through the oil-feed pipe A', the fourway connection a4, and the stuffing-box a5, and has a threaded connect-ion in the supporting bracket arm at. By means of the hand-Wheel a7 the valvespindle may be rotated to diminish or increase the area of the oil-exit open ing, as required.

The oil passes from the nozzle in a thin wide sheet, and is therefore more easily vaporized. The inner end of the oil-feed pipe A has a threaded engagement With the corresponding end of the oil-nozzle, and is provided With the stuffing-box b, closing the back end of the steam-nozzle, Which'also serves as a slip-joint, so that the steam-nozzle may have a slight movement on said feed-pipe in adjusting said nozzle. The gland-nut b is provided with radial lugs b2 (see Fig. 4) for the` purpose of conveniently adjusting the same.

The steam-supply pipe A2 is inserted in the upper side of the steam-nozzle. One end of the adjusting-rod E is secured to said pipe at apoint close t the steam-nozzle, the opposite threaded end passing through the post b3, which in turn is screwed into the four-Way connection a4. On the rod E and on each side of the post b3 are placed the adjustingnuts CZ d', for the purpose of adjusting and locking the steam-nozzle in the position to which it maybe adjusted.

The arrangement and relative position of the steam and oil nozzles' obviate all danger from explosions andaccidents that have attended the use of a number of oil-burners wherein the flame is liable to be extinguished by the steam, especially when the iiame is turned W, and before it was discovered thc furnace filled with a highly-explosive gas which Would explode when an attempt Was made to relight the burner, thereby causing serious accidents. This cannot occur with the present burner, as the oil and steam enter through separate passages, the arrangement being such that the' steam cannot choke l or otherwise prevent a continuous and uniform feed through the oil-nozzle. Neither can the oil-passage become clogged, as is the case Where the steam and oil both pass through the same opening.

In operation theburner is first properly arranged iu the combustion-chamber and provided With the steam and oil connections. The oil may be fed by gravity or forced by a pressure-feed. In the first process of lighting a fire of some suitable combustible matter is started around theV burner and the oilvalve thenslowly opened to start the feed in thev form of spray. The steam is then turned on, and by reason of the Wedge-shaped burner injected intol the oil-fiame from above and below and eects a complete vaporization of the combustible products, a much less volume of steam being required than under the ordinary arrangements.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a liquid-fuel burner, the combination, with the outer nozzle or shell having longitudinal interior grooves and a flattened discharge end, of an inner nozzle of the form of the discharge end of the nozzle of the outer shell, having lateral projections which enter vthe said longitudinal grooves, an oil-tube to Which said inner nozzle is attached, and means for adjusting said nozzle, substantially as def scribed.
